argapp - A Python package for CLI application development

Overview

argapp is an OOP wrapper for argparse and argcomplete:

• Allows writing CLI applications using OOP - encapsulates argparse API.
• Provides limited support for the shell completion via argcomplete.

Full documentation is available at https://deohayer.github.io/argapp-ws.

Features

• Offers several classes for CLI parsing via OOP.
  • Arg represents optional and positional arguments, with the most essential use cases covered.
  • App represents a main command or a subcommand.
  • The fields are validated upon construction or setting, raising an Exception in case of any issues.
  • The parsing can be overridden by subclassing Arg.
• Offers shell completion support if argcomplete is installed:
  • The required API calls are already in place. It is only required to install argcomplete and add the PYTHON_ARGCOMPLETE_OK comment to the script.
  • Specific completions are added automatically.
